Influence of electrode pretreatment, counter anions and additives on the electropolymerization of pyrrole in aqueous solutions

Almost completely dedoped electrochemically deposited luminescent films exhibiting excellent LED performance

“…In the ED processes, the anion of the supporting electrolyte is incorporated into the oxidized (doped) ED film and released from the reduced (dedoped) ED film in order to ensure charge neutrality. Many reported results indicate that the anion plays an important role in ED processes [39][40][41][42][43][44][45]. The conductivity and morphology of ED films strongly depends on the nature and the size of the anions used in the polymerization solutions; however, the mechanistic effects from the anion size are not clear.…”

Synthesis and characterization of conductive polypyrrole/multi-walled carbon nanotubes composites with improved solubility and conductivity

“…After dissolution in a polar solvent, the conductivity reduced into 10 À2 S/cm when cast into a film. Several reports also reveal that the physical properties of fabricated PPy strongly depend on the types of surfactants/organic acids [19,20]. Nevertheless, conductive PPy with onedimensional nanostructure are seldom mentioned among these reports.…”

Impedance Analysis of Growth and Morphology of Electropolymerized Polypyrrole Nanocomposites

“…On the other hand, the morphology of the electrochemically synthesized conducting polymers depends on deposition conditions [10]. In all, when the film thickness of the polymer is less than 100 nm, ordered and homogeneous structures are developed [9].…”
